Skin is called skin because it forms a protective layer over the body, just like an animal’s skin.
It acts as a barrier against harmful external agents such as ultraviolet radiation, pollutants, and other physical irritants. It also helps to regulate body temperature by releasing sweat when the body gets too hot or shivering when it is cold.
In addition to protection, skin has many other important functions. For instance, it produces vitamin D which helps with bone formation and muscle growth; sebum which keeps the skin hydrated; and melanin which provides pigment so that our skin color can vary from person to person. Additionally, within the dermis layer of our skin are nerve endings responsible for sensing touch and pressure these help us interpret what’s happening around us in terms of temperature changes or pain receptors sending signals back to our brain.
Apart from its practical uses, our skin also plays an aesthetic role in how we look and feel about ourselves. There may be some genetic factors involved but there are many things we can do as individuals to keep our skin looking healthy like moisturizing regularly or avoiding excessive sun exposure without sunscreen protection (which is why wearing sunscreen is so important!). We can also use products like cleansers help remove dirt from pores while nourishing ingredients like antioxidants provide additional benefits by helping repair damage caused by environmental stressors on a daily basis.
